[css] How to make a div with a circular shape?

i want to create a div with background color red and completely circular in shape

How can i do that?

Css or jquery both can be used

Use a border-radius property of 50%.

So for example:

.example-div {

    border-radius: 50%

}

By using a border-radius of 50% you can make a circle. Here is an example:

CSS:

#exampleCircle{
    width: 500px;
    height: 500px;
    background: red;
    border-radius: 50%;
}

HTML:

<div id = "exampleCircle"></div>

HTML div elements, unlike SVG circle primitives, are always rectangular.

You could use round corners (i.e. CSS border-radius) to make it look round. On square elements, a value of 50% naturally forms a circle. Use this, or even a SVG inside your HTML:

document.body.innerHTML+='<i></i>'.repeat(4);

i{border-radius:50%;display:inline-block;background:#F48024;}
svg {fill:#F48024;width:60px;height:60px;}
i:nth-of-type(1n){width:30px;height:30px;}
i:nth-of-type(2n){width:60px;height:60px;}

<svg viewBox="0 0 120 120" xmlns="http://www.w3.org/2000/svg">
  <circle cx="60" cy="60" r="60"/>
</svg>

.circle {
    border-radius: 50%;
    width: 500px;
    height: 500px;
    background: red;
}

<div class="circle"></div>

see this FIDDLE

You can do following

FIDDLE

<div id="circle"></div>

CSS

#circle {
    width: 100px;
    height: 100px;
    background: red;
    -moz-border-radius: 50px;
    -webkit-border-radius: 50px;
    border-radius: 50px;
}
